Asked about the cards that his dad left in his lunch, Ethan said: "I thought that even if I m at school i still feel like daddy is still with me."

Speaking about how school dealt with the tragedy, Ethan said: "My teaching assistant helped me because she let me make these cards so that when i feel sad or lonely I can write these cards and have some time out."

The presenter revealed that his son was back at school within a week, explaining: "I wanted to encourage him because this is the biggest thing he's going to face."
